REMOVABLE CALK FOR HORSESHOES.

Specification of Letters Patent.

Patented May 9, 1911.

Application filed July 21, 1910. Serial No. 573,028.

To all whom it may concern."

Be it known that I, HENRY D. l/VENDT, a citizen of the United States,and a resident of Hoboken, in the county of Hudson and State of NewJersey, have invented a new and Improved Removable Calk for Horseshoes,of which the following is a full, clear, and exact description.

This invention relates to certain improvements in removable horseshoecalks, adapted for use in connection with the ordinary form of horseshoeto prevent the horse from slipping on icy or slippery ground.

In my improved construction, I employ a calk-bearing plate ofsubstantially the same general form as the horseshoe and this plate isso constructed that it engages with the shoe to prevent any lateralmovement of the calk-bearing plate, and is clamped over the hoof in sucha manner that no portion of the clamping means comes adjacent the rearand tender side of the hoof. The calks proper are removable from theplate, and may be readily replaced when worn or broken.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures, and in which Figure 1 is a sideelevation of a device constructed in accordance with my invention, andillustrated as applied to the hoof; Fig. 2 is an inverted plan view ofthe parts shown in Fig. 1; Fig. 3 is a perspective view of my improveddevice removed from the hoof and shoe; and Fig. 4: is a perspective viewof one of the calks.

My improved device includes a calk-bearing plate 10, which is preferablyof substantially the same general shape as the horseshoe, and adapted toengage with the under surface of the latter. The calk-bearing plate atthe rear ends of its two side portions is provided with upwardly-turnedflanges 11, which may engage with the rear ends of the horseshoe, so asto prevent the calk-bearing plate from slipping forwardly. Directly inadvance of these flanges, are openings 12, which may receive thedownturned heel calks A on the shoe proper B. The engagement of thesecalks A within the openings 12, prevents forward, rearward or lateralmovement of the calk-bearing plate in respect to the shoe. The plate 10,at its front edge, is cut away so as to leave a space for the toe-calk Oof the horseshoe, and the plate engages with the rear surface of thistoe-calk, so as to additionally prevent forward movement of thecalk-bearing plate. The plate is provided with a series of apertures 13therein, along opposite sides, and within each of these apertures thereis inserted a removable calk 14, preferably of the form illustrated inFig. 4. Each .aperture 13 is countersunk, and each calk is provided witha head, which will fit into this countersunk portion, so as to liesubstantially flush or slightly above the upper surface of thecalk-bearing plate. The calks are thus prevented from falling outthrough the apertures, and, at the same time, are rigidly held in place.

For securing the calk-bearing plate to the horseshoe, the plate hasriveted thereto, upon opposite sides, bracket members 15, each of whichmay be formed of a metal plate bent to form a portion for engagementwith the under surface of the plate 22, and a portion extending upwardlyat right angles thereto for engagement with the outer edge of the plateand with the outer edge of the horseshoe. These brackets may be securedin place in any suitable manner, as, for instance, by suitable rivets.There are two of these brackets upon each side, and fromthe two rearbrackets, stra s 16 and 17 extend upwardly and forwarc ly so as topermit of their being buckled together upon the front of the hoof at aconsiderable distance above the shoe. Preferably, these straps extendupwardly and forwardly at an angle of about 45 degrees. From eachforward bracket, a strap 18 extends up wardly and rearwardly, the lowerend of the strap being secured to the bracket and the upper end of thestrap being secured to the adjacent first-mentioned strap.

In fastening the device on the hoof, it is merely necessary to place theplate in en gagemcnt with the under side of the shoe with the heel calksof the latter extending down through the openings 12 in the plate. Uponbuckhn the straps 16 and 17, the device will be crawn forwardly, so thatthe flanges 11 will engage with the rear ends of the shoe and the frontof the plate will engage with the rear side of the toe calk. The strainexerted on the device as the horse pulls, will tend to move the shoerearwardly in respect to the plate, and the toe calks, the heel calksand the flanges 11 restrain upon the straps is that necessary to holdthe device firmly in place.

Having thus described my invention, 1-

claim as new and desire to secure by Letters Patent: v

1 A device of the class described, including a plate adapted forengagement beneath the under surface of the shoe and of the same generalform as the shoe, said plate being provided with a recess at its frontedge adapted to receive the toe calk of the shoe and engage with therear side of the latter, and having apertures adjacent the rear ends andadapted to receive the heel calks of the shoe, said plate being furtherprovided with rear ends bent upwardly, brackets separate from said plateand secured against the under side thereof, said brackets havingupturned portions engaging the outer edge of the shoe, straps connectedwith said upturned portions and adapted to be secured together in frontof-the hoof above the shoe, and ealks removably carried by said plateand extending through said brackets and having heads disposed betweensald plate Gopies of this patent may be obtained for five cents each, byaddressing the Commissioner of Patents,
